What two factors should pesticide applicators focus on to minimize spray drift?

Focusing on droplet size and wind direction and speed is crucial for minimizing spray drift when applying pesticides. Droplet size plays a significant role because smaller droplets are more susceptible to being carried off by wind, whereas larger droplets tend to settle more quickly and are less likely to drift. By selecting the appropriate droplet size, applicators can mitigate the risk of unintended pesticide movement away from the target area.

Additionally, understanding wind direction and speed is essential for effective application. Applying pesticides with the wind at your back can help ensure that the spray reaches the intended target and reduces the likelihood of drift into non-target areas. Ideal wind conditions typically involve lower speeds, as higher winds can lead to significant drift and may cause pesticide to affect unintended surfaces or areas.

This focus on droplet size and wind conditions is fundamental for safe and effective pesticide application, ensuring compliance with regulations and minimizing environmental impact.
